There is no minimum number of schools that you must rank for the Match. You can rank as many as you would like, up to 15. Remember that the Match is binding, so you should only rank schools you are certain you would be willing to attend if matched. (Note: MIT is the only college partner that is non-binding.)
Remember that your National College Match Rankings are due by October 13 at 11:59 p.m. Pacific Time. If you do not submit any rankings by this deadline, you will be automatically opted out of the Match and will be eligible to apply only through QuestBridge Regular Decision.
